This patent application is the U.S. national phase of International Patent Application No. PCT/JP2014/051102, filed Jan. 21, 2014, which claims the benefit of Japanese Patent Application No. 2013-008239, filed on Jan. 21, 2013, which are incorporated by reference in their entireties herein.
The present invention relates to an agent for elevating nitric oxide (NO) concentration comprising glutathione or a salt thereof as an active ingredient, in which prevention or amelioration of a vascular endothelial malfunction-related symptom, or vasodilation and blood flow-promoting effects through a higher NO concentration elevating action in vivo can be expected.
NO is a gaseous substance having various physiological functions as a signal. NO produced from vascular endothelial cells is called an endothelium-derived relaxing factor (EDRF), and has various physiological activities for maintaining normal vascular function, such as a blood vessel relaxation action, an oxidized LDL inhibitory action, a platelet aggregation inhibition action, an anti-smooth muscle cell proliferation action, and an anti-oxidative action (Non-Patent Document 1).
Arteriosclerosis is a state in which the elasticity of a vascular wall is reduced by hyperactivity of an inflammatory reaction in the vascular intima or accumulation of cholesterol. As a result, a smooth blood flow is less likely to be maintained, and thrombus is likely to be formed. As one of the factors, a decrease in the NO production ability of vascular endothelial cells has been pointed out by a number of studies. In this way, NO is a very important regulator for vascular function, and thus, studies to prevent or ameliorate a vascular endothelial malfunction such as arteriosclerosis have been proceeded by attempts to enhance the NO production ability of vascular endothelial cells (Non-Patent Documents 1 and 2). Further, in recent years, usefulness of NO in daily activities has been focused, and, for example, studies to increase the training efficiency by improving exercise performance, increasing oxygen consumption efficiency, or improving muscle metabolism by increasing the NO concentration in the body during exercise have been reported (Non-Patent Document 3). That is, by enhancing the NO production ability of vascular endothelial cells, in addition to the prevention or amelioration of an ischemic vascular disease due to a vascular endothelial malfunction such as arteriosclerosis, for example, increase in exercise efficiency or the like in daily activities can be expected.
Glutathione is a tripeptide consisting of glutamic acid, cysteine, and glycine, and glutathione plays a central role in a removal mechanism of the reactive oxygen species in vivo. Furthermore, glutathione is also involved in a detoxification mechanism by which xenobiotics are removed from the body. A hepatoprotective action (Non-Patent Document 4) and a whitening action (Non-Patent Document 5) by ingestion of glutathione have been reported. From such functionalities, glutathione is used as an antidote at the time of poisoning or medicine for improving liver function, or a food material for anti-oxidation.
So far, it has been reported that, when glutathione is administered intravenously to a human who is observed to have arteriosclerosis, the blood vessel relaxation response caused by acetylcholine administration which is an NO production stimulant in a vascular endothelium is enhanced (Non-Patent Document 6). In addition, it has been reported that, when a removed aorta of a rabbit was treated with a drug, the glutathione concentration in vascular tissues was lowered, and vasodilation was induced by addition of an NO donor, and thus the vasodilation action due to the NO donor was improved by combined addition of glutathione (Non-Patent Document 7).
However, these prior reports relate to studies performed under limited special experimental conditions such as a condition that the NO donor is externally added, a condition that a removed vessel is evaluated, or a condition that glutathione synthesis is inhibited and the endogenous glutathione concentration is depleted, and it has not been known at all that the NO concentration in vivo is increased by administration of only a glutathione substance into an animal.
An object of the present invention is to provide an agent for elevating NO concentration which exhibits prevention or amelioration of a vascular endothelial malfunction-related symptom, or vasodilation and blood flow-promoting effects through a higher NO concentration elevating action in vivo, and is effective for prevention or amelioration of an ischemic disease, exercise performance improvement, muscle metabolism improvement, lipid accumulation suppression, skin quality improvement, memory and learning ability improvement, attention concentration improvement, shoulder stiffness amelioration, amelioration of excessive sensitivity to cold, or swelling suppression.

Although, as the agent for elevating NO concentration according to the present invention, glutathione or a salt thereof as it is can be directly ingested or administered, usually, glutathione or a salt thereof is desirably provided as various product forms or formulations.
Although the product or formulation comprises glutathione or a salt thereof as an active ingredient, the product or formulation may further comprises any active ingredient. In addition, the product or formulation is manufactured by mixing the active ingredient together with one or more types of pharmaceutically acceptable carriers and by any method well known in the technical field of pharmaceutics.
As the ingestion or administration form of the product or formulation, it is desirable to use the most effective form when the NO concentration is increased in the body, and examples thereof include oral ingestion or oral administration, or, for example, parenteral administration such as intravenous administration, intraperitoneal administration, and subcutaneous administration; and, oral ingestion or oral administration is preferable.
The ingestion or administration form, or the dosage form may be, for example, any of oral agents such as a tablet, a powder, a granule, a pill, a suspension, an emulsion, an infusion⋅decoction, a capsule, a drink, a solution, an elixir, an extract, a tincture, and a fluid extract, and parenteral dosages such as an injection, a drop, a cream, and a suppository; and, an oral agent is suitably used.
A liquid preparation such as a drink, which is suitable for ingestion or oral administration, can be formulated by adding water, sugars such as sucrose, sorbitol, and fructose, glycols such as polyethylene glycol and propylene glycol, oils such as sesame oil, olive oil, and soybean oil, antiseptics such as p-hydroxy benzoic acid esters, paraoxybenzoic acid derivatives such as methyl paraoxybenzoate, preservatives such as sodium benzoate, flavors such as strawberry flavor and peppermint, or the like.
For example, a tablet, a powder, a granule, or the like, which is suitable for oral ingestion or administration, can be formulated by adding sugars such as lactose, saccharose, glucose, sucrose, mannitol, and sorbitol, starch such as potato, wheat, and corn, inorganic substances such as calcium carbonate, calcium sulfate, sodium hydrogen carbonate, and sodium chloride, excipients such as crystalline cellulose and vegetable powders including a licorice powder and a gentian powder, disintegrators such as starch, agar, a gelatin powder, crystalline cellulose, carmellose sodium, carmellose calcium, calcium carbonate, sodium hydrogen carbonate, and sodium alginate, lubricants such as magnesium stearate, talc, hydrogenated vegetable oil, macrogol, and silicone oil, binders such as polyvinyl alcohol, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose, carmellose, gelatin, and a starch glue solution, surfactants such as fatty acid ester, plasticizers such as glycerin, or the like.
To the product form or formulation which is suitable for oral ingestion or administration, an additive generally used in foods and drinks, for example, sweeteners, colors, preservatives, thickening stabilizers, antioxidants, color formers, bleaching agents, anti-fungal agents, gum bases, bittering agents, enzymes, brightening agents, acidulants, seasonings, emulsifiers, toughening agents, agents for manufacture, flavors, spice extracts, or the like may be added.
The product form or formulation which is suitable for oral ingestion oral administration can be manufactured by processing into a tablet, a powder, a granule, a pill, a suspension, an emulsion, an infusion⋅decoction, a capsule, a drink, a solution, an elixir, an extract, a tincture, or a fluid extract of a unit packaging form per ingestion according to an ingestion period, the number of times of ingestion, or an ingestion amount.
For example, “a unit packaging form per ingestion” is a form in which the amount to be ingested per one time is predetermined, and “a unit packaging form per a week to three months” is a form in which the amount to be ingested for a week to three months is included. As the unit packaging form, examples thereof include a form in which a certain amount is defined by using a pack, a packaging, a bottle, or the like is exemplified.
For example, as “a unit packaging form per ingestion”, in a case where the product form or formulation is a drink, examples thereof include a form in which a drink in which 10 mg or more of glutathione or a salt thereof is suspended or dissolved is put into a bottle or the like in a form of an amount to be drunk per ingestion.
For example, as “a unit packaging form per a week to three months”, in a case where the ingestion amount per day, in one ingestion per day, is 300 mg, and a tablet comprises 50 mg of glutathione or a salt thereof, examples thereof include a form in which 42 tablets to 540 tablets are packaged.
For example, an injection suitable for parenteral administration is preferably formed of a sterilized aqueous agent comprising glutathione or a salt thereof which is isotonic to blood of a recipient. For example, in the case of an injection, a solution for injection is prepared using a carrier or the like formed of a salt solution, a glucose solution, or a mixture of a salt solution and a glucose solution.
Even in these parenteral agents, one or more supplementary components selected from antiseptics, preservatives, excipients, disintegrators, lubricants, binders, surfactants, plasticizers, and the like listed for the oral agent can be used.
Although the concentration of the glutathione or a salt thereof in the agent for elevating NO concentration according to the present invention is suitably selected depending on the product form or the type of formulation, or the effect or the like expected by ingestion or administration of the product or formulation, the concentration is usually 0.1% by weight to 100% by weight, preferably 0.5% by weight to 80% by weight, and particularly preferably 1% by weight to 70% by weight, in terms of glutathione or a salt thereof.
Although the amount of ingestion or administration and the number of ingestion or administration of the agent for elevating NO concentration according to the present invention vary depending on the ingestion or administration form, the age, the body weight, or the nature or the severity of a symptom to be treated of a person in need of ingestion or administration, usually, administration is performed once or several times a day such that the dose usually becomes 10 mg to 10 g, preferably 50 mg to 50 g, and particularly preferably 100 mg to 1 g per day for an adult, in terms of glutathione or a salt thereof.
The ingestion or administration period is not particularly limited, but is usually one day to one year, preferably three days to six months, and more preferably one week to three months.
The agent for elevating NO concentration according to the present invention can be used to exhibit prevention or amelioration of a vascular endothelial malfunction-related symptom, or vasodilation and blood flow-promoting effects through a higher NO concentration elevating action in vivo. Since prevention or amelioration of a vascular endothelial malfunction-related symptom, or effective vasodilation effective blood flow-promoting effects can be expected from the agent for elevating NO concentration according to the present invention, the agent can be applied to prevention or amelioration of an ischemic disease, exercise performance improvement, muscle metabolism improvement, lipid accumulation suppression, skin quality improvement, memory and learning ability improvement, attention concentration improvement, shoulder stiffness amelioration, amelioration of excessive sensitivity to cold, or swelling suppression.
The method of the present invention can be used for preventing or ameliorating the symptom by the agent for elevating NO concentration according to the present invention being ingested by a subject in need of elevating the NO concentration in the body, a subject who desires a physiological effect by elevation of the NO concentration, or a subject who exhibits the symptom or being administered to the subject.
In the present invention, the glutathione or a salt thereof can be used for the manufacture of the agent for elevating NO concentration.

Hereinafter, the present invention will be described in more detail with reference to Examples; however, the present invention is not limited thereto. Test Examples in which NO concentration elevating effect of glutathione is examined will be shown below. Test Examples
Eight-week-old male SD rats were purchased from Japan SLC, Inc. Under isoflurane anesthesia, a catheter was indwelled in a carotid artery, and after awakening, the rats were acclimatized for one week. The rats were allowed to freely ingest solid feed (CE-2, manufactured by Clea Japan, Inc.) and tap water, and reared at a temperature of 20° C. to 24° C. and a humidity of 50% to 60% in a light and darkness cycle for 12 hours. In addition, reduced glutathione manufactured by Kyowa Hakko Bio Co., Ltd. was used. After acclimatization, a blood sample of a baseline was taken using the catheter indwelled in the carotid artery. Next, purified water (control group), 25 mg/kg/day of reduced glutathione (glutathione-25 mg/kg group), or 50 mg/kg/day of reduced glutathione (glutathione-50 mg/kg group) was forcibly administered orally to each rat once a day for three days, and blood collection was performed immediately before the last administration and for 4 hours after the last administration over time using the catheter indwelled in the carotid artery. Moreover, the rats were fasted for 16 hours before the last administration. After obtaining blood plasma from the blood sample, the concentrations of nitrite (NO2″) and nitrate (NO3″) which are stable NO metabolites in the blood were determined by a HPLC method (ENO-20, EICOM). That is, the NO concentration in the blood was expressed as NOx which is the sum of these, and the amount of increase in the NOx from the baseline at the time of each blood collection was calculated.
